where their hearts are offered to gods who sanctioned conquest. every city and town in the empire pays tribute in exact amount and kind as specified by the aztecs, or risks horrible consequences. in the forests and jungles of other realms, maya kings rule great cities with the force of their own personalities. they build temples and huge stone billboards to prop up royal dynasties that have little actual power. they perform gruesome rituals that require the skins of other people. they go to war and capture players for their ball games -- games where the losers never play again. today, inside ancient pyramids, archaeologists face real danger to bring the story of these kings and their politics out of the past. before the arrival of europeans, two extraordinary civilizations flourished in mesoamerica. both the aztecs and the maya had cultures of startling sophistication, and political systems that were enormously complex. archaeologists are intrigued by ancient political systems. they want to know how these systems were organized and how they evolved. archaeologist arthur demarest. throu
with its ethnic and religious minorities. in the city of lanzhou. but lanzhou's location-- and its future-- on this frontier have much to do with the region's physical geography and naral resources. ( blowing heavily ) narrator: for centuries in this part of china, rafts like this were an important means of transportation. made of sheepskin, inflated and tied together, these rafts, called yangpi fazi, navigated the huang he, or yellow river. by looking only at the huang he, you might think lanzhou is a wet place. in fact it only receives about 12 inches of rain a year. geographer chai yangwei, in the green, follows these farmers to see how they cope with such low rainfall. peculiar to agriculture in this area, these are called "stone fields." a thin layer of stones is spread over the surface of the field to hold in moisture. stone fields can be used for about eight years. constant upkeep is necessary, however. this plot is two years old. the farmers are adding fertilizer. if the soil becomes mixed with the stones, the efficiency of a stone field decreases, so stones must be carefully swep
geography has contributed to densely populated cities, and made japan one of the most highly urbanized countries in the world. over 80% of its population lives in urban areas. tokyo is japan's largest city. as the capital, it is the focus of most legal, pitical, and economic activities in the nation. most large corporations have their headquarters here. everything tends to concentrate in tokyo. 32 million people, or one out of every four japanese live within a 30-mile radius. while tokyo casts a large shadow, it covers only three percent of the total land mass of japan. land prices here have skyrocketed. a booming economy in the 1980s and early 1990s saw profits go into real estate speculation, contributing to a bubble of inflated values. affordable housing was in short supply. more and more people began moving out to the suburbs to fulfill their dream of owning a home. by the mid-90s, japan hit an economic slump and thasian economic crisis of 1997 hit. the bubble burst and land prices began to decline, but not by much. housing prices in tokyo are falling, but they're still at very hig
-brick city of albi in the south of france. henri grew up in a world of chateaus and privilege in a family living on the fruits of its noble past. but a france governed by the middle class was losing its taste for nobility. like many aristocrats, his father alphonse retreated into rural pastimes-- riding and hunting. an eccentric, he looked wistfully back to the family's glorious past. alphonse had married his first cousin adele, a common practice in a class anxious to preserve the purity of its bloodlines. but the results of inbreeding for henri were uncommonly cruel. his legs were short and weak. he broke each of them in early adolescence and stopped growing when he was 14. he was just under five feet tall. his head, hands and torso continued to develop. but his stunted legs made walking painful for the rest of his life. denied the aristocratic pleasures of riding and hunting, henri turned to sketching and painting rural scenes. he had a flair for it and in 1882, at the age of 18, he moved to paris to study painting. it was a move that would change the direction of his art and his life.
collection of city-states. at palenque, tonina, bonampak and other cities, dynastic kings ruled absolutely, controlling trade and tribute. they presided over intricate hierarchies of nobles and officials at courts resplendent with works of art. maya culture, shrouded in a mystery as dense as the forests in which it took root, revealed itself fitfully over three centuries. when the ruins in the jungle were first discovered, there was no way of understanding how the civilization was organized. so it's really through the inscriptions that we've been able to identify kings, to find out their capitals, their seats of power. and through this, we recognize now that there were many kingdoms. there was no unified maya state. there wasn't even just a few states. there were many, many states. (narrator) the first inroads into understanding the maya were made by spanish missionaries in the 16th and 17th centuries who followed in the imperial wake of hernan cortes. their "discoveries" included the ruins at copan. but interest ithe st civilizaon began to accelerate in the 18th century when father antoni

artist joan miro. born in the catalan city of barcelona in 1893, miro has remained close to the land and its people. but as a young man in paris, he joined th friends like max ernst and jean arp in the emerging surrealist movement of the 1920s. in his painting "the farm," miro's characteristic symbols and themes began to appear: serpentine shapes, checkerboard patterns, infinite sce represented by the moon or a star. in 1922, he painted "the farmer's wife," the ancestress of countless female symbols that also became a continuing motif in miro's art. in 1924, his art broke free of gravitational constraints in theurrealistic world of "harlequin's carnival." over the years, he developed his own personal symbolism, and in the 1950s, the scale of his art grew with such works as a mural at harrd university and "the wall ofhe sun" for unesco in pas. as his work grew in size, miro continued what he termed "a process of simplification." he stated, "little by little, i have managed to reach a point at which i use no more than a small number of forms and colors this process found a culminating
. by 1550 bc, power had shifted to a n kingdom 500 miles south in the ancient city of thebes, now called luxor. to the west, in the hills beyond the nile's west bank, the royal tombs of the valley of the kings were cut into limestone cliffs. their interiors are richly decorated with hieroglyphs and paintings-- signs and symbols that detail the necessary steps to attain immortality. egypt's power and the grandeur that came with it were well-established by 2500 bc when the great pyramids at giza were built. the sphinx was a philosophy of government set in stone. it depicted the king as fearless, cunning and brave as the lion. and as crucial to egypt as the nile itself. the king was not just a political leader but a religious leader too. in the minds of the ancient egyptians, the pharaoh's power and authority as a king stretched far beyond the boundaries of his country-- and into the cosmos itself. after death, he would escape the earthly bounds of his tomb, board a solar boat and sail into immortality. this vision became material in objects and images founin the tombs and temples as a way
rupture city, honey, rupture city, you're going to be in trouble. so they tell you let your mouth open and let the air come out and it keeps coming out, out, out. where did all that air come, you've got compressed air down there. and you let your mouth-- let the air come out as you rise. so you don't all of a sudden blow up like this and really hurt yourself. you wanna see what an exam question would be on a balloon question like this, gang? here is an exam question in there. as this balloon starts to sink, will it sink all the way to the bottom? how many people say, "oh no, it'll get down "to a certain elevation like everything and kind of just stop, even rocks, man." you throw a rock overboard, it'll finally go down, the pressure will get so much it'll just kind of hang there. they all are scuba diver types, have you done that? they'll say, "watch out for those rocks, honey." rocks hanging in the air. when you throw a rock off, does it sink all the way to the bottom? and will that balloon sink all the way to the bottom? okay, now here is a question i got to ask you. as this balloon s
. and most--the little particles make up... take 133 million tons. that's several city blocks. scrunch all those atoms up, 133 million tons, scrunch them up until all these things here cave into one another. you got the size of a pea. so take the size of a pea and spread out a city block, that's how atoms are, most of them. so these things go right through our body without ever making a direct hit. you get, maybe, one direct hit per year on the average, one got me, okay? very, very seldom, okay? you know what? 1987, the supernova-- the supernova in the heavens-- and showered the whole universe with neutrinos. and neutrino flecks were so enormous that about one out of every 248 people, something like that, got one of those neutrinos, caught one and the rest went just right by through us, right through the other side, never, never making a direct hit. why? because the space between the little particles of the atom are enormous compared to the size of the particular nucleons or electrons. kinda neat, huh? so if there's a great big beam of neutrons coming right by, you just walk right through
pan. oh, you burn yourself. tattoo city, honey. you have burned yourself. take that same frying pan, this time, pour a little water in it. now, put the wat-filled frying pan on the stove, tu around, the telephone ring. [makes noise] "what's it--no, no, "i don't want any aluminum siding on my house. thank you anyway." boom. you come back later, a few minutes later, put your hand on the water, huh, - it's okay? - it's okay. it's okay? if you can do that, you can do that, it's okay. now, i got a question for you, which do you suppose has more internal energy? which has absorbed more heat, the frying pan empty or the frying pan with the water in it? think. i'm not asking which has got the higher temperature. i'm asking a different question. i'm saying, which has absorbed the most heat? and your neighbor says... -- what's the answer, gang? the water. the water has absorbed more heat. but you know what? it's not as hot. the tempature is not so high. so some substances will absorb an awful lot of heat for only a small change in temperature. iron, put a little heat energy in it, whoop, the
that pond. the pond is getting deeper and deeper and the city workmen come out and they stuck some boards, like shelving boards, just pine lumber, one-inch pine lumber. it turns out right on those slots. and that's what they were. they were slots to hold some boards for when the dam got extra deep. and son of a gun, if that dam didn't fill up just up like that-- [makes sound] --and these boards are holding back tons and tons of water. we kids look at that and we say, "gee, if the board does that, what was the concrete for?" let me ask you a question. could it have made it with all that board? no. what would happen to the dam, honey? begin with s-p, end with loosh. [laughter] sploosh. okay? so it turn-- how about if a great, big ship comes by here? [makes sound] that board still gonna hold that water back? if there's no-- answer ends with a p. yup. yup. now, if the water is moving-- [makes sound] --a lot of momentum of the water is gonna crash into the boat, that's different. but if the water is still, gets deeper and deeper, that water pressure against here depends only on the density of
